The present invention relates to the field of microwave antenna and particularly to transmitting and receiving planar antenna design having an omni-directional radiation pattern for ultra wideband applications. The cover is provided with a number of elongated tubular extensions axially projecting therefrom that are each partially slotted to provide a plurality of cantilevered fingers. A converter for converting linearly and circularly polarized waves is provided on the mirror surface of the main reflector. A pivot pin is removably received by the first and second openings. In one embodiment, the steps include measuring a predetermined parameter at predetermined observation window times and dynamically adjusting allocated bandwidth for parent classes of real-time traffic by adjusting an average of the predetermined parameter to have a value within a predetermined stable region. In a second configuration, an asymmetrical, enhancement mode, Junction Field Effect Transistor is connected with a transformer such that the source and the drain serve as the two leads of a two terminal circuit.
